Just after 0800hrs Friday March 22nd Liverpool Fire Dept was requested mutual aid to Moyers Corners for a possible apartment fire. Initial reports indicated an electrical fire in a bedroom. Upon arrival MCFD B1 arrived to a 3 story garden style apartment with smoke showing. First arriving units encountered heavy fire and smoke within the apartment. Liverpool Engine 3(Capt.

The Truck arrived as the second due Truck and began outside vent and laddering the building.
